Hi @kippi1950, I found several discussion in Connect with members who have MDS or loved ones with the condition.
I’m posting a few below for you. There are conversations as well. You can find those by typing in MDS in the top search bar. There will be a list of related discussion for you.

The first site is an article about MDS posted Hematology that you might find helpful.

It’s understandable to be concerned about the possibility of developing another health condition such as MDS or AML years after treatments with chemotherapy. We’ll be optimistic that this isn’t what your wife is dealing with. Please let me know what you find out with her next appointment. Wishing her (and you) only good news.
